IMPROVED ROW-LOOK.

lO ALL WHOM IT MAY CON CERN Be it known tha. I, WILLIAM FUzzARD, of Chelsea, in the county of Suolk, and State of Massachusetts, have invented a new and improved Application of Row-Locks to Boats; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable -others skilled in the art to make'and use the same, reference being had to the accompanying drawing, forming a part of this specification.

l This invention consists in applying row-locks to boats, in such a manner that instead of the row-locks being xcd or stationary, ashitherto, they will be altered to move under the action-oi` the oar-s, in a. direction towards and from the operator or oarsman, while in the act of rowing, and. thereby materially increase the length of the stroke or sweep of the blade of the oars, and corespondently augment the eiciency of the same in their propelling action.

The accompanying drawing represents a plan or top view of a row-boat with my invention applied to it.

Y A is the boat, constructed in any of the known styles or forms, and having at each side of it a semicircular bar, B, rmly secured or attached; said bars projecting horizontally from the boat, and each having a curved slot, a, made through it, through which the lower parts of the row-locks C pass, and are allowed to move freely back and forth in the slots. The row-lock, which is fitted in the slot of one of the bars B, has a. toothed segment, D, attached, which gears into a segment, E, iirmly secured to one side of the boat, as clearly shown in the drawing, and by having the row-lock connected with this gearing the former will be moved as the oar is moved in the act of rowing, to wit, moved from the oarsman when the inner ends or handle portion' ofthe oars are drawn towards him, and moved towards him when the inner ends or handle portions are shoved outward from him, the row-locks, therefore, moving in a direction corresponding with that of the outer parts or blades of the oars, thereby materially increasing thc length ofthe sweep of the blades, and augmenting their eiciency or propelling power in a corresponding degree or ratio. With fixed row-locks', the sweep-of the oars is designated by the dotted red lines b b, but with the movable row-lock, the length of sweep is increased to thepoints c c, as clearly indicated in the drawing. The row-lock is retained in proper position .by means of aradius-bar, d, shown in dotted lines attached to its lower end, and pivoted to the segment E, concentric therewith.

Various plans may bc devised for eccting this movement of the row-locks. On vthe oppositel side of the boat to that where the plan just described is applied, the row-lock has a' segment, F, attached to its lower end, and to the ends of this segment cords e e are attached, which cross each other, and are connected to the ends ofthe bar B, or to the gunwale of the boat, as shown atff, a radius-bar, G, retaining the row-lock in position. By thismodication the same movement will be given the row-lock as by the plan first described.

I do not confine myself` to any particular means or arrangement of means for thus giving automatically a movement to the row-lock from the oars, for an indefinite number of plans may be devised for the purpose.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The application of row-locks to a. row-boat, in such a manner that the' former will, during the operation of rowing, be moved automatically from the motion of the oarsifor the purpose of increasing thelength of the sweep ofthe same, substantially as set forth.
